FDA Delays Hereditary Angioedema NDA Decision
FDA has told KalVista Pharmaceuticals that it will not meet a 6/17 user fee review action target data for its NDA for sebetralstat, indicated for treating hereditary angioedema (HAE). The agency said the goal date would not be met due to heavy workload and limited resources, according to the company, adding that a decision on the submission would be made within four weeks. Such a delay is presumably related to recent reduction in force staff terminations at the agency.
“The FDA has not requested additional data or studies and has not raised any concerns regarding the safety, efficacy or approvability of sebetralstat,” the company says. “KalVista has addressed all prior information requests in a timely manner, and the company believes the only remaining item under FDA review is the finalization of the labeling.”
Sebetralstat is described by the company as an investigational oral plasma kallikrein inhibitor. HAE is a rare genetic disease resulting in deficiency or dysfunction in the C1 esterase inhibitor protein and subsequent uncontrolled activation of the kallikrein-kinin system, it says. People living with HAE experience painful and debilitating attacks of tissue swelling in various locations of the body that can be life-threatening depending on the area affected.
